- a well system can include a wellbore that can be formed in a subterranean formation for extracting produced hydrocarbon or other suitable material.
- a wellbore operation can be performed to extract the produced hydrocarbon material or perform other suitable tasks relating to the wellbore.
- a tubular such as a casing string, a production string, surface piping, or the like, can be used to perform or facilitate the wellbore operation.
- the tubular may be exposed to harsh conditions that may degrade the tubular over time or may otherwise affect the integrity of the tubular.
- FIG. 1 is a schematic of a well system with a tubular according to one example of the present disclosure.
- FIG. 2 is a schematic a system for tubular evaluation using vibration according to one example of the present disclosure.
- FIG. 3 is a schematic of a system for tubular evaluation using vibration according to one example of the present disclosure.
- FIG. 4 is a schematic of a system for tubular evaluation using vibration according to one example of the present disclosure.
- FIG. 5 is a top view of a measurement tool that can be used in tubular evaluation according to one example of the present disclosure.
- FIG. 6 is a flowchart of a process for evaluating a tubular using vibration according to one example of the present disclosure.
- FIG. 7 is a block diagram of a computing device for evaluating a tubular using vibration according to one example of the present disclosure.
- Certain aspects and examples of the present disclosure relate to causing a tubular to vibrate and detecting the vibrations to evaluate the tubular and a cement layer associated with the tubular.
- the tubular can be pipe associated with drilling a wellbore, casing the wellbore, producing fluids in the wellbore, or other suitable wellbore operations. Examples of tubulars may include drill pipe, surface pipe, casing, production tubing, pipeline, etc.
- the cement layer can be provided in an annulus between the tubular and a subterranean formation surrounding the wellbore. The cement layer can seal the annulus and maintain a position of the tubular in the wellbore.
- a vibration-inducing device can provide an electromagnetic pulse, a mechanical pulse, an acoustic pulse, or other suitable energy pulse or mechanism for causing the tubular to vibrate.
- a hammer device or a roller device can be used for causing vibration along the tubular via mechanical pulses.
- an electromechanical pulse (EMP) generator can be used as a vibration-inducing device by producing electromagnetic pulses.
- an acoustic transducer may transmit acoustic pulses to cause the tubular to vibrate.
- the vibration can be detected using laser interference measurement techniques. Examples of laser interference measurement techniques may include laser distance meters, laser vibrometers, lidar systems, etc.
- the measurements provided by the laser interference measurement techniques can be used to generate data for evaluating the tubular.
- the data may indicate deformation or corrosion of the tubular.
- the data may also indicate a quality of a bond between the cement layer and the tubular.
- evaluating the tubular in the wellbore that contains, for example, gas can be improved.
- suitable logging fluid can be any clear logging fluid such as a completion brine, or other brine.
- the casing may be vibrated by a device producing an electromagnetic pulse, a magnetic pulse, a mechanical pulse, an acoustic pulse, or other suitable energy pulse.
- lasers may be used to detect the vibration of the casing.
- the lasers can be coupled to a measurement tool that can be positioned downhole in the wellbore.
- the lasers can be optically directed toward the casing using beam splitters and turning optics.
- the lasers can be used in laser interference measurement devices to provide laser vibration measurements, laser distancing measurements, or a combination thereof.
- Laser vibration measurements can be a frequency, amplitude, or other measurement associated with vibration.
- the laser distancing measurements can be a distance between two objects, such as a laser vibrometer and the tubular. Examples of the laser interference measurement devices can include laser distance meters, laser vibrometers, lidar systems, and the like.
- the laser distancing measurements may be used to determine or adjust a position of the measurement tool within the wellbore.
- vibration in the tubular can be induced by electromechanical pulses and a laser vibrometer can detect the vibration.
- the laser vibrometer can be sensitive to a large range of frequencies and the electromagnetic pulses can generate a large range of frequency pulses.
- the frequencies detected by the laser vibrometer can indicate a thickness of the tubular. Therefore, the laser vibrometer and electromechanical pulses can evaluate tubulars of varying thicknesses. Concentric tubulars can also be evaluated using the laser vibrometer and electromechanical pulses. Additionally, multiple interfaces, such as the cement layer, the wellbore, the subterranean formation, or a combination thereof may be evaluated.
- the use of laser interference techniques can mitigate an influence of eccentricity and specular reflection on the data obtained from vibration of the tubular.
- the laser vibrometer can detect a vibrational wave rather than an acoustic wave
- measurements of frequency, amplitude, etc. by the laser vibrometer can be independent of eccentricity and specular reflection.
- the laser distancing measurements can be used to determine a frequency of an electromagnetic pulse or an acoustic pulse based on a distance between the laser vibrometer and the tubular.
- the lasers can be positioned to detect vibration at a correct location. At the correct location measurements can be independent of eccentricity and specular reflection.
- the correct location can be associated with a phase shift of echoes from the electromagnetic pulse or the acoustic pulse.
- the lasers may be rotated along a window portion of the measurement tool or other suitable portions of the measurement tool to enable detection at the correct location.
- multiple locations may be monitored along the casing by positioning multiple laser interference measurement devices in the measurement tool.
- the multiple locations can be monitored for vibration simultaneously.
- the multiple location monitoring can be used to deconvolute three dimensional effects of echoes associated with electromagnetic pulses, acoustic pulses, or the like.
- positioning the multiple laser interference measurement devices in the measurement tool may provide high resolution azimuthal monitoring.
- monitoring may be conducted simultaneously along multiple azimuths and across multiple points colinear to the wellbore axis by positioning multiple measurement tools with multiple laser interference measurement devices at different depths in the wellbore. By positioning the multiple measurement tools at different depths, propagation of the vibration along the tubular can be monitored.
- the system may be used in low temperature wells including those for gas storage.
- the lasers can be placed in eutectic cooling with optical routing of a laser beam path.
- layered eutectic cooling may be possible with a small package of the laser diodes.
- a laser beam may be routed for multiple purposes such as laser ranging at multiple spots along the tubular for accurate eccentricity calculations or for monitoring multiple spots along different depths of the tubular simultaneously.
- the lasers may be inherently temperature robust.
- fibers may transmit the laser beam from a cooler location such as the eutectic cooler or the surface.

The sour environment may cause the tubular 102 to degrade due to the material, such as the carbon-based steel, of the tubular 102 interacting with the sour environment. Additionally, pressure from the subterranean formation 106 or other suitable environmental characteristics of the subterranean formation 106 may cause deformations in the tubular 102 or may cause degradation of a bond between the tubular 102 and the cement layer 110 . Thus, the integrity of the tubular 102 and the quality of the bond between the tubular 102 and the cement layer 110 may be measured, estimated, predicted, or the like to prevent failure of the tubular 102 while positioned with respect to the wellbore 104 .

During the wellbore operation, a tubular, such as a casing string, a production string, surface piping, or the like, can be used to perform or facilitate the wellbore operation. The tubular may be exposed to harsh conditions that may degrade the tubular over time or may otherwise affect the integrity of the tubular.

FIG. 7 is a block diagram of a computing device for evaluating a tubular using vibration according to one example of the present disclosure. - Certain aspects and examples of the present disclosure relate to causing a tubular to vibrate and detecting the vibrations to evaluate the tubular and a cement layer associated with the tubular. The tubular can be pipe associated with drilling a wellbore, casing the wellbore, producing fluids in the wellbore, or other suitable wellbore operations. Examples of tubulars may include drill pipe, surface pipe, casing, production tubing, pipeline, etc. The cement layer can be provided in an annulus between the tubular and a subterranean formation surrounding the wellbore. The cement layer can seal the annulus and maintain a position of the tubular in the wellbore. A vibration-inducing device can provide an electromagnetic pulse, a mechanical pulse, an acoustic pulse, or other suitable energy pulse or mechanism for causing the tubular to vibrate. For example, a hammer device or a roller device can be used for causing vibration along the tubular via mechanical pulses. Additionally, an electromechanical pulse (EMP) generator can be used as a vibration-inducing device by producing electromagnetic pulses. As another example, an acoustic transducer may transmit acoustic pulses to cause the tubular to vibrate. Additionally, the vibration can be detected using laser interference measurement techniques. Examples of laser interference measurement techniques may include laser distance meters, laser vibrometers, lidar systems, etc. The measurements provided by the laser interference measurement techniques can be used to generate data for evaluating the tubular. The data may indicate deformation or corrosion of the tubular. The data may also indicate a quality of a bond between the cement layer and the tubular.
- In some examples of the present disclosure, evaluating the tubular in the wellbore that contains, for example, gas can be improved. Additionally, some examples of the present disclosure can be applied to a wellbore containing any suitable logging fluid. For example, suitable logging fluid can be any clear logging fluid such as a completion brine, or other brine. In an example, the casing may be vibrated by a device producing an electromagnetic pulse, a magnetic pulse, a mechanical pulse, an acoustic pulse, or other suitable energy pulse. Additionally, lasers may be used to detect the vibration of the casing. The lasers can be coupled to a measurement tool that can be positioned downhole in the wellbore. The lasers can be optically directed toward the casing using beam splitters and turning optics. The lasers can be used in laser interference measurement devices to provide laser vibration measurements, laser distancing measurements, or a combination thereof. Laser vibration measurements can be a frequency, amplitude, or other measurement associated with vibration. The laser distancing measurements can be a distance between two objects, such as a laser vibrometer and the tubular. Examples of the laser interference measurement devices can include laser distance meters, laser vibrometers, lidar systems, and the like. The laser distancing measurements may be used to determine or adjust a position of the measurement tool within the wellbore.
- In an example, vibration in the tubular can be induced by electromechanical pulses and a laser vibrometer can detect the vibration. The laser vibrometer can be sensitive to a large range of frequencies and the electromagnetic pulses can generate a large range of frequency pulses. The frequencies detected by the laser vibrometer can indicate a thickness of the tubular. Therefore, the laser vibrometer and electromechanical pulses can evaluate tubulars of varying thicknesses. Concentric tubulars can also be evaluated using the laser vibrometer and electromechanical pulses. Additionally, multiple interfaces, such as the cement layer, the wellbore, the subterranean formation, or a combination thereof may be evaluated.
- In some examples, the use of laser interference techniques can mitigate an influence of eccentricity and specular reflection on the data obtained from vibration of the tubular. For example, as the laser vibrometer can detect a vibrational wave rather than an acoustic wave, measurements of frequency, amplitude, etc. by the laser vibrometer can be independent of eccentricity and specular reflection. Additionally, the laser distancing measurements can be used to determine a frequency of an electromagnetic pulse or an acoustic pulse based on a distance between the laser vibrometer and the tubular. In some examples, the lasers can be positioned to detect vibration at a correct location. At the correct location measurements can be independent of eccentricity and specular reflection. For example, the correct location can be associated with a phase shift of echoes from the electromagnetic pulse or the acoustic pulse. In some examples, the lasers may be rotated along a window portion of the measurement tool or other suitable portions of the measurement tool to enable detection at the correct location.
- In some examples, multiple locations may be monitored along the casing by positioning multiple laser interference measurement devices in the measurement tool. The multiple locations can be monitored for vibration simultaneously. In an example, the multiple location monitoring can be used to deconvolute three dimensional effects of echoes associated with electromagnetic pulses, acoustic pulses, or the like. Additionally, positioning the multiple laser interference measurement devices in the measurement tool may provide high resolution azimuthal monitoring. In some examples, monitoring may be conducted simultaneously along multiple azimuths and across multiple points colinear to the wellbore axis by positioning multiple measurement tools with multiple laser interference measurement devices at different depths in the wellbore. By positioning the multiple measurement tools at different depths, propagation of the vibration along the tubular can be monitored.
- Certain examples of the system may be used in low temperature wells including those for gas storage. To apply examples of the system in a higher temperature well, the lasers can be placed in eutectic cooling with optical routing of a laser beam path. Additionally, layered eutectic cooling may be possible with a small package of the laser diodes. In an example, a laser beam may be routed for multiple purposes such as laser ranging at multiple spots along the tubular for accurate eccentricity calculations or for monitoring multiple spots along different depths of the tubular simultaneously. In some examples, the lasers may be inherently temperature robust. Additionally, fibers may transmit the laser beam from a cooler location such as the eutectic cooler or the surface.

The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions are used to describe the illustrative aspects, but, like the illustrative aspects, should not be used to limit the present disclosure.

FIG. 1 is a schematic of awell system 100 with a tubular 102 according to one example of the present disclosure. Thewell system 100 can include awellbore 104 that can extend through asubterranean formation 106. Thesubterranean formation 106 can include hydrocarbon material such as oil, gas, coal, or other suitable material. In some examples, the tubular 102 can extend from awell surface 122 into thesubterranean formation 106. The tubular 102 can provide a conduit through which formation fluids, such as production fluids produced from thesubterranean formation 106, can travel to thewell surface 122. Additionally, the tubular 102 can allow awell tool 108 to be positioned in thewellbore 104 for performing one or more wellbore operations. The tubular 102 can be coupled to walls of thewellbore 104 via cement or other suitable coupling material. For example, acement layer 110 can be positioned or formed between the tubular 102 and the walls of thewellbore 104 for coupling the tubular 102 to thewellbore 104. The tubular 102 can be coupled to thewellbore 104 using other suitable techniques. Additionally, while illustrated as a downhole tubular, the tubular 102 may instead be or include a surface tubular, such as a pipeline. - In some examples, the tubular 102 can include carbon-based steel or other suitable types of carbon-based steel alloys. Additionally, in an example, the
wellbore 104 can include or provide a sour environment that includes water, carbon dioxide, hydrogen sulfide, or any combination thereof. The sour environment may cause the tubular 102 to degrade due to the material, such as the carbon-based steel, of the tubular 102 interacting with the sour environment. Additionally, pressure from thesubterranean formation 106 or other suitable environmental characteristics of thesubterranean formation 106 may cause deformations in the tubular 102 or may cause degradation of a bond between the tubular 102 and thecement layer 110. Thus, the integrity of the tubular 102 and the quality of the bond between the tubular 102 and thecement layer 110 may be measured, estimated, predicted, or the like to prevent failure of the tubular 102 while positioned with respect to thewellbore 104. - The
well system 100 can also include acomputing device 140 that can analyze data associated with vibration the tubular 102 to evaluate the tubular 102 with respect to the environment provided by thewellbore 104 or thewell system 100. Thecomputing device 140 can be positioned at thewell surface 122 of thewell system 100. In some examples, thecomputing device 140 can be positioned downhole in thewellbore 104, remote from thewell system 100, or in other suitable locations with respect to thewell system 100. Thecomputing device 140 can be communicatively coupled to any suitable component such as thewell tool 108, devices embedded in thewell tool 108 such as a laser vibrometer, a laser distance meter, etc. For example, as illustrated inFIG. 1 , thecomputing device 140 can include anantenna 142 that can allow thecomputing device 140 to receive and to send communications relating to thewell system 100, the tubular 102, and the like. Thecomputing device 140 can receive data relating to vibration of the tubular 102. Thecomputing device 140 can use the received data to determine a status of the tubular 102, a status of thecement layer 110, or a combination thereof. In some examples, thecomputing device 140 can output the status of the tubular 102, the status of thecement layer 110, or a combination thereof for use in optimizing the tubular 102 with respect to thewell system 100. The design of the tubular 102, the position of the tubular 102, repairs to the tubular 102, and the like can be optimized. -
FIG. 2 is a schematic a system fortubular 202 evaluation using vibration according to one example of the present disclosure. The tubular 202 can correspond to the tubular 102 ofFIG. 1 and thewellbore 204 can correspond to thewellbore 104 ofFIG. 1 . As depicted, the tubular 202 can be a downhole tubular that can be positioned in thewellbore 204. The tubular 202 may include a casing string, a tubing string, or the like. The tubular 202 can transport material produced from thewellbore 204, material for use in thewellbore 204, etc. Acement layer 210 can be positioned or formed between the tubular 202 and asubterranean formation 214 for protecting the tubular 202, positioning the tubular 202, coupling the tubular 202 to walls of thewellbore 204, or a combination thereof. The tubular 202 can include aconveyance mechanism 212. Theconveyance mechanism 212 may be a cable conveyance mechanism such as slickline, downhole tractors, or wireline. Theconveyance mechanism 212 may also be a pipe conveyance mechanism such as drill pipe or a cable-pipe conveyance mechanism such as coiled tubing. Additionally, ameasurement tool 206 can be coupled to theconveyance mechanism 212 for positioning themeasurement tool 206 downhole in thewellbore 204 and within the tubular 202. - A vibration-inducing device (not depicted) can cause vibration in the tubular 202. For example, the vibration-inducing device can be a Lorentz force device. In an example, the Lorentz force device can include one or more permanent magnets and one or more current carrying coils to generate electromagnetic pulses that can cause the tubular 202 to vibrate. A mechanical jar or mechanical hammer can generate mechanical pulses that can cause the tubular 202 to vibrate. Additionally, a roller device with an irregular pattern can move along a length of the tubular 202 and the irregular pattern contacting the tubular 202 can cause the tubular 202 to vibrate.
- Additionally, an
interferometer 208 can be coupled with themeasurement tool 206. In some examples, themeasurement tool 206 may rotate to position theinterferometer 208. Theinterferometer 208 can be a device for measuring the interference pattern between two or more sources of light. In some examples, theinterferometer 208 can be a laser interferometer such as a Michelson laser interferometer, a laser vibrometer, etc., or theinterferometer 208 can be another suitable device for detecting vibration. Laser distancing devices, such as a laser distance meter, may also be coupled with themeasurement tool 206 for detecting a distance between themeasurement tool 206 and the tubular 202. - In some examples, the vibration-inducing device can cause vibration in the tubular 202 and the
interferometer 208 can detect the vibration. For example, the Lorentz force device can cause vibration of the tubular 202 and theinterferometer 208 can detect the vibration. Theinterferometer 208 can be a laser vibrometer. The laser vibrometer may be a two-beam laser interferometer that can use the Doppler effect to measure vibration. The Doppler effect can be a change in frequency due to reflection of a wave off of a moving object (e.g., the vibrating tubular 202). The laser vibrometer can analyze an interference pattern between a laser beam directed to the tubular 202 and a reference laser beam not directed to the tubular 202. The laser vibrometer can, via analysis of the interference pattern, determine a doppler shift of the laser beam reflecting off the tubular 202 during vibration. An amplitude and frequency of the laser beam can be extracted from the Doppler shift and can be used to determine a status of the tubular 202, a status of thecement layer 210, or a combination thereof. The status of the tubular 202 may be associated with detecting damage to the tubular 202. The status of thecement layer 210 may be associated with detecting damage to thecement layer 210 or detecting an area of thecement layer 210 not sufficiently sealing the annulus between thewellbore 204 and the tubular 202. - For example, the amplitude of a vibrational wave, a light wave, or other suitable wave detected by the
interferometer 208 can be a magnitude of the vibration experienced by the tubular 202. The amplitude of an energy wave reflected off the tubular 202 may be indicative of the stress experienced by the tubular 202 due to the vibration. A higher amplitude can be associated with higher stress, which can suggest that the tubular 202 has undergone damage, the tubular 202 may be prone to damage, or a combination thereof. Additionally, the frequency of the vibration of the tubular 202 can be used to determine a thickness of the tubular 202. Thus, the frequency of vibration of the tubular 202 can also be indicative of damage to the tubular 202. For example, a segment of the tubular 202 with a high frequency of vibration may be thinner than a segment of the tubular 202 with a lower frequency of vibration. Additionally, damping of the energy wave detected by theinterferometer 208 can be a measure of a reduction of the amplitude of the energy wave. The damping of the energy wave can be used to determine an impedance of thecement layer 210. In an example, a high impedance can indicate a strong bond between the tubular 202 and thecement layer 210. -
FIG. 3 is a schematic of asystem 300 fortubular 302 evaluation using vibration according to one example of the present disclosure. The tubular 302 can be positioned in awellbore 304. Acement layer 310 can be positioned in an annulus between the tubular 302 and asubterranean formation 314 surrounding thewellbore 304. The system can include aconveyance mechanism 312 coupled to measurement tools 306 a-c. Theconveyance mechanism 312 can position the measurement tools 306 a-c within the tubular 302. Additionally, interferometers 308 a-c can be coupled to the measurement tools 306 a-c. The interferometers 308 a-c can be positioned, via the coupling with the measurement tools 306 a-c, a distance apart to facilitate measurements of vibration at multiple locations along a length of the tubular 302. - In some examples, one or more vibration-inducing devices can cause vibration at one or more locations along the length of the tubular 302 and the interferometers 308 a-c can detect the vibration at the one or more locations. The positioning of the interferometers 308 a-c can enable evaluation of the tubular 302 and the
cement layer 310 at multiple depths. Thesystem 300 can detect vibration via a pulse-echo configuration or thesystem 300 can detect vibration via a pitch-catch configuration. In the pulse-echo configuration the vibration can be detected at a location an electromagnetic pulse, acoustic pulse, mechanical pulse, or other suitable energy pulse caused the vibration. In the pitch-catch configuration the vibration can be caused by the energy pulse at first location and the vibration can be detected at a second location as the vibration propagates along the length of the tubular 302. Additionally, in an example, a vibration-inducing device can cause vibration at a location on the tubular 302 and the interferometers 308 a-c can detect, at multiple locations, a propagation of the vibration along the length of the tubular 302. The interferometers 308 a-c may simultaneously detect the vibration at the multiple locations or the interferometers 308 a-c may stagger detection by a certain amount of time. -
FIG. 4 is a schematic of asystem 400 fortubular 402 evaluation using vibration according to one example of the present disclosure. The tubular 402 can be positioned in awellbore 404. Acement layer 410 can be formed in an annulus between the tubular 402 and asubterranean formation 414 surrounding thewellbore 404. Thesystem 400 can include aconveyance mechanism 412 coupled to ameasurement tool 406. Theconveyance mechanism 412 can position themeasurement tool 406 within the tubular 402. Interferometers 408 a-b can be coupled to themeasurement tool 406 and can be positioned along an edge of the measurement tool 406 a distance apart. - In some examples, the interferometers 408 a-b can facilitate measurements of vibration at multiple locations along an azimuth of the tubular 402. In an example, each of the interferometers 408 a-b can be associated with an energy pulse to provide multiple pulse-echo configurations along the azimuth of the tubular 402. The detection of vibration of the tubular 402 by the interferometers 408 a-b can be used to determine frequency values, amplitude values, or other suitable measurements for a segment of the tubular. The frequency values, amplitude values, or other suitable measurements can be averaged or otherwise used in combination to determine a status of the segment of the tubular 402, a status of a segment of the
cement layer 410 associated with the segment of the tubular, or a combination thereof. Additionally, by detecting vibration at multiple locations along the azimuth of the tubular 402, the frequency values, the amplitude values, and the other suitable measurements can be independent of eccentricity. Thus, themeasurement tool 406 can be positioned in a location non-central relative the tubular 402 and accurate data can be generated to evaluate the tubular 402. The use of the interferometers 408 a-b can further enable evaluation of the tubular 402 without requiring rotation or repositioning of themeasurement tool 406. - Additionally, or alternatively, the
system 400 can include laser distancing devices such as laser distancing meters. The laser distancing devices can be used to measure one or more radial distances from the interferometers 408 a-b to the tubular 402. The laser distancing devices can, via the one or more radial distances, guide positioning of aninterferometer 408 a within a section of themeasurement tool 406 or positioning of themeasurement tool 406 within the tubular 402. In some examples, frequency, amplitude, or other suitable measurements can be dependent on eccentricity. Thus, the one or more radial distances can be used to position themeasurement tool 406 in a center of the tubular 402. Additionally, in some examples, an echo of an energy wave detect by the interferometers 408 a-b can be independent of eccentricity when detected as a particular location. Thus, the laser distancing devices can be used to position the interferometers 408 a-b to detect the echo at the particular location. -
FIG. 5 is a top view of ameasurement tool 506 that can be used in tubular evaluation according to one example of the present disclosure. In some examples, interferometers 508 a-d can facilitate measurements of vibration at multiple locations along an azimuth of a tubular. In an example, each of the interferometers 508 a-d can be associated with an energy pulse to provide multiple pulse-echo configurations along the azimuth of the tubular. Additionally, the use of the interferometers 508 a-d can enable evaluation of the tubular without requiring rotation or repositioning of themeasurement tool 506. - Additionally, or alternatively, the
measurement tool 506 can be coupled to additional devices associated with multiple laser measurement techniques. For example, the additional devices may include laser distancing meters, laser vibrometers, LiDAR systems, or other suitable laser measurement devices or techniques. The interferometers 508 a-d, the additional devices, or a combination thereof can be used to generate data that can be used to determine parameters associated with the tubular. For example, vibrational frequency data can be used to determine a thickness of the tubular. Additionally, amplitude data can be used to determine a damping of the vibrational wave. The damping of the vibrational wave can be used to determine the impedance of the cement layer. The parameters can further be used to determine a status of the cement layer, a status of the tubular, or a combination thereof. -
FIG. 6 is a flowchart of aprocess 600 for evaluating a tubular 202 using vibration according to one example of the present disclosure. Aspects ofFIG. 6 are discussed in reference toFIG. 2 . The tubular 202 can experience deformation, corrosion, or other suitable damage while positioned in awellbore 204. Additionally, acement layer 210 can be positioned adjacent to the tubular 202 to seal an annulus between the tubular 202 and thewellbore 204. Thecement layer 210 may also experience damage over time or a bond between thecement layer 210 and the tubular 202 may degrade over time. Thus, the tubular 202 can be evaluated to determine a status of the tubular 202 or a status of thecement layer 210. For example, a status of the tubular can indicate damage to the tubular 202. Additionally, the status of thecement layer 210 can indicate a lack of contact between the tubular 202 and thecement layer 210. - At
block 602, thesystem 200 can deploy, via aconveyance mechanism 212, ameasurement tool 206 downhole in thewellbore 204 that includes the tubular 202 therein. Theconveyance mechanism 212 may position themeasurement tool 206 at a depth in the tubular 202 to obtain data associated with a particular portion of the tubular 202. The tubular 202 may include a downhole tubular that can be positioned in awellbore 204, a surface tubular that can be positioned at the surface of a well system, or a combination thereof. The downhole tubular can include a casing string, a tubing string, or the like, and the surface tubular can include a surface pipeline, etc. The tubular 202 can be used with respect to one or more wellbore operations. Theconveyance mechanism 212 can be any suitable apparatus for deploying themeasurement tool 206 such as wireline, slickline, or drill pipe. Themeasurement tool 206 can be a rotating or stationary head coupled to a portion of theconveyance mechanism 212. - At
block 604, thesystem 200 can induce, via the vibration-inducing device, vibration in the tubular 202. In an example, thesystem 200 can position the vibration-inducing device to cause the tubular 202 to vibrate at a location along the length of the tubular 202. The vibration-inducing device can be positioned using theconveyance mechanism 212, themeasurement tool 206, or other suitable components associated with thewellbore 204 ortubular 202. The vibration-inducing device can be a Lorentz force device or other suitable device that can generate electromagnetic pulses to cause the vibration in the tubular 202. The vibration-inducing device can also be a mechanical hammer, a mechanical jar, a roller device, or other suitable device that can generate mechanical pulses to cause the vibration in the tubular 202. Additionally, a speaker or other suitable device can generate acoustic pulses to cause the vibration in the tubular 202. - At
block 606, thesystem 200 can detect, via aninterferometer 208 coupled to themeasurement tool 206, the vibration in the tubular 202 to generate data that is useable to determine at least one status of the tubular 202 and at least one status of thecement layer 210. Theconveyance mechanism 212 and themeasurement tool 206 can position theinterferometer 208 to detect the vibration in the tubular 202 at a particular location. Theinterferometer 208 can be positioned by rotation of themeasurement tool 206. In some examples, themeasurement tool 206 can include sections and theinterferometer 208 can be positioned within the sections. Additionally, in some examples, theinterferometer 208 can be a laser interferometer such as a Michelson laser interferometer, a laser vibrometer, or the like. The laser interferometer can be optically directed using, for example, beam splitters, turning optics, or other suitable devices, to detect the vibration in the tubular 202 at the particular location. - In an example, the laser interferometer can analyze an interference pattern between a laser beam reflecting off the tubular 202 during vibration and a reference laser beam that does not interact with the tubular 202. The data, such as frequency data, amplitude data, and other suitable data can be obtained from analysis of the interference pattern. The data can be used to determine parameters associated with the tubular 202 or the
cement layer 210, determine a status of the tubular 202, determine a status of thecement layer 210, or a combination thereof. For example, the frequency data can be used to determine a thickness of the tubular 202. The thickness can be used to determine the status of the tubular 202 including, for example, whether the tubular 202 has experienced corrosion. Additionally, the amplitude data can be used to determine an impedance of thecement layer 210. The impedance of thecement layer 210 can be used to determine the status of thecement layer 210 including, for example, whether thecement layer 210 is securely bonded to the tubular 202. - Additionally or alternatively, the
system 200 can include a computing device. Thesystem 200 may, via the computing device, receive data associated with the vibration of the tubular 202 as detected by theinterferometer 208. The computing device may, determine, based on the data, the parameters associated with the tubular 202. For example, thesystem 200 can detect, by theinterferometer 208, at least one vibrational wave and determine a damping of the at least one vibrational wave. The damping of the at least one vibrational wave can be a measure of oscillatory decay of the at least one vibration wave. The oscillatory decay of the at least one vibrational wave can be due to interaction with the tubular 202, propagation through a medium, other suitable factors affecting the at least vibrational wave, or a combination thereof. Additionally, an impedance of a segment of thecement layer 210 can be determined based on the damping of the at least one vibrational wave. The impedance of the segment of thecement layer 210 can be a measure of resistance to the vibration imposed on the tubular 202. For example, a tubular 202 with a strong bond to thecement layer 210 may resist vibration and cause significant oscillatory decay of the at least one vibrational wave. Thesystem 200 can also determine a frequency of the vibration in the tubular. The frequency can be a number of vibrations that occur in a given amount of time, and can be indicative of a thickness of the tubular 202. - Additionally, the
system 200 may, via the computing device, determine, based on the parameters, at least one status of the tubular 202 and at least one status of thecement layer 210. For example, a parameter can be a high impedance due to thecement layer 210 increasing tubular resistance to vibration. Thus, as an example, the status of thecement layer 210 can indicate a strong bond between the segment of thecement layer 210 and the tubular 202. Additionally, a first frequency associated with a first segment of the tubular 202 can be lower than a second frequency associated with a second segment of the tubular 202. This may indicate the first segment of the tubular 202 has a greater thickness than the second segment of the tubular 202. Thus, a status of the second segment of the tubular 202 can indicate corrosion or damage to the second segment of the tubular 202. - In some examples, the
system 200 may execute an adjustment to a position of theinterferometer 208 based on a target location for detecting the vibration of the tubular 202. For example, the target location can be a location for which measurements obtained can be independent of eccentricity. Additionally, thesystem 200 may execute an adjustment to a position of themeasurement tool 206 based on the target location, at least one distance between themeasurement tool 206 and the tubular 202, or a combination thereof. The adjustments to the interferometer and the measurement tool can facilitate accurate and comprehensive evaluation of the tubular 202 and thecement layer 210. - Additionally or alternatively, the
system 200 can position a plurality of interferometers a distance apart relative to the length of the tubular 202 and position the plurality of interferometers axially relative to the tubular 202 (e.g., as depicted inFIG. 3 ). Thesystem 200 may detect, via the plurality of interferometers, vibrations as more than one location along the length of the tubular 202. Thesystem 200 may also position a second plurality of interferometers a distance apart along an edge of themeasurement tool 206 and position the second plurality of interferometers azimuthally relative to the tubular 202 (e.g., as depicted inFIG. 4 ). Thesystem 200 may detect vibration at multiple locations along an azimuth of the tubular 202 via the second plurality of interferometers. Additionally, thesystem 200 may determine, via the second plurality of interferometers, at least one radial distance between the second plurality of interferometers and the tubular 202. In some examples, laser distancing meters, lidar, or other suitable laser measuring techniques can also be integrated in themeasurement tool 206. - In a particular example, the tubular 202 can include multiple measurement tools positioned a distance apart (e.g., as depicted in
FIG. 3 .). Additionally, the multiple measurement tools can have multiple interferometers (e.g., as depicted inFIG. 4 andFIG. 5 ). Thus, vibration can be detected at multiple depths of the tubular 202 and along multiple azimuths associated with the multiple depths to generate comprehensive data for evaluating the tubular 202. -
FIG. 7 is a block diagram of acomputing device 140 for evaluating a tubular using vibration according to one example of the present disclosure. The components shown inFIG. 7 , such as aprocessor 704, amemory 710, apower source 722, an input/output 708, and the like may be integrated into a single structure such as within a single housing of acomputing device 140. Alternatively, the components shown inFIG. 7 can be distributed from one another and in electrical communication with each other. - The
computing device 140 can include theprocessor 704, thememory 710, and abus 706. Theprocessor 704 can execute one or more operations for evaluating the tubular positioned in awellbore using data 714 associated with vibration of the tubular. Theprocessor 704 can executeinstructions 712 stored in thememory 710 to perform the operations. Theprocessor 704 can include one processing device or multiple processing devices or cores. Non-limiting examples of theprocessor 704 include a Field-Programmable Gate Array (“FPGA”), an application-specific integrated circuit (“ASIC”), a microprocessor, etc. - The
processor 704 can be communicatively coupled to thememory 710 via thebus 706. The non-volatile memory may include any type of memory device that retains stored information when powered off. Non-limiting examples of thememory 710 may include EEPROM, flash memory, or any other type of non-volatile memory. In some examples, at least part of thememory 710 can include a medium from which theprocessor 704 can readinstructions 712. A computer-readable medium can include electronic, optical, magnetic, or other storage devices capable of providing theprocessor 704 with computer-readable instructions or other program code. Nonlimiting examples of a computer-readable medium include (but are not limited to) magnetic disk(s), memory chip(s), ROM, RAM, an ASIC, a configured processor, optical storage, or any other medium from which a computer processor can readinstructions 712. Theinstructions 712 can include processor-specific instructions generated by a compiler or an interpreter from code written in any suitable computer-programming language, including, for example, C, C++, C#, Perl, Java, Python, etc. - In some examples, the
memory 710 can be a non-transitory computer readable medium and can includecomputer program instructions 712. For example, thecomputer program instructions 712 can be executed by theprocessor 704 for causing theprocessor 704 to perform various operations. For example, theprocessor 704 can receivedata 714 associated vibration of a tubular. The vibration can be caused by a vibration-inducing device and the vibration can be detected by an interferometer coupled to a measurement tool. Theprocessor 704 can further determine, based on thedata 714,parameters 715 associated with the tubular and a cement layer. The cement layer can be positioned between the tubular and a subterranean formation surrounding the wellbore. Additionally, theprocessor 704 can determine, based on theparameters 715, at least one status of the tubular 716 and at least one status of acement layer 718. - In some examples, the
processor 704 may receive thedata 714 from a plurality of interferometers. Thus, thedata 714 can be associated with vibration at more than one location along the length of the tubular. Additionally, theprocessor 704 may receivedata 714 from a second plurality of interferometers. Thedata 714 can be associated with at least one radial distance between a second plurality of interferometers and the tubular. - In some examples, the
parameters 715 determined by theprocessor 704 can include a damping of at least one vibrational wave associated with vibration of the tubular, a frequency of the vibration of the tubular, or other suitable parameters. Additionally, theprocessor 704 can determine, based on the damping of the at least one vibrational wave, an impedance of a segment of the cement layer. The impedance can indicate a resistance to vibration of the segment of the cement layer, a segment of the tubular associated with the segment of the cement layer, or a combination thereof. The impedance can be used to determine the status of thecement layer 718, such as the status of the bond between the segment of the cement layer and the segment of the tubular. Additionally, in an example, theprocessor 704 can determine a first impedance of a first segment of the cement layer and can determine a second impedance of a second segment of the cement layer. Theprocessor 704 may generate, based on the second impedance being less than the first impedance, an alert 720 for a user, the alert 720 associated with the status of thecement layer 718 and the alert providing an indication of a disruption to a bonding of the cement layer and the tubular. - The
processor 704 may further determine, based the frequency of the vibration of the tubular, a thickness of a segment of the tubular. The thickness of the segment of the tubular can be used to determine a status of the tubular 716. For example, the status of the tubular 716 can be associated with damage to the tubular since, for example, a damaged segment of the tubular may be less thick than a nondamaged segment of the tubular. In an example, theprocessor 704 may determine a first thickness of a first segment of the tubular and determine a second thickness of a second segment of the tubular. The processor may generate, based on the second thickness being less than the first thickness, the alert 720 for a user, the alert 720 associated with the status of the tubular 716 and the alert 720 providing an indication of damage to the tubular. In some examples, additional alerts, statuses, or a combination thereof can be generated by theprocessor 704. - The
computing device 140 can additionally include the input/output 708. The input/output 708 can connect to a keyboard, a pointing device, a display, other computer input/output devices or any combination thereof. An operator or other suitable user may provide input using the input/output 708. Data relating to the wellbore, the tubular, the cement layer, or a combination thereof can be displayed to an operator or other suitable user related to a wellbore operation through a display that is connected to or is part of the input/output 708. The displayed values can be observed by the operator, a supervisor, or other suitable user related to a wellbore operation, who can adjust the wellbore operation based on the displayed values. The displayed value can be an alert associated with the status of the tubular 716, the status of thecement layer 718, or a combination thereof. Alternatively, thecomputing device 140 can, instead of displaying the values, automatically control or adjust the measurement tool, the interferometer, the tubular, or other component associated with the wellbore operation based on the displayed values. For example, theprocessor 704 may execute an adjustment to a position of the interferometer based on a target location for detecting vibration in the tubular. Additionally, theprocessor 704 may also execute an adjustment to a position of the measurement tool based on at least one distance between the measurement tool and the tubular. - In some aspects, systems and methods for downhole status detection using vibration are provided according to one or more of the following examples:
